Hi, I’m renovating my kitchen and want to run a cable from the consumer unit to the outside wall while I’m at it. In the future, I plan to install a split-room AC or an air-to-air heat pump to serve three indoor units. I assume the indoor units are powered by cables coming from the outdoor unit, alongside all the piping, etc. I’m not sure about the unit ratings yet, but it will be a typical residential setup. Would 6mm twin and earth cable be suitable for this?
